Etiology of tubal infertility

Etiology of tubal infertility

Patients who have suffered from adnexitis, suppurative appendicitis, tuberculous peritonitis, tuberculosis and endometriosis, patients with incomplete abortion, fever, abdominal pain and puerperal infection after induced abortion, patients with sexually transmitted diseases such as gonorrhea and patients with fallopian tube malformation may all lead to abnormal fallopian tube function and tubal infertility.

Effusion of fallopian tube

Tubal effusion means that after pathogens infect fallopian tubes, swollen intima will be formed in fallopian tubes under the infiltration of white blood cells, edema will appear in interstitium, and mucosal epithelium will fall off. If it is not treated in time and effectively, tubal pus will be formed. After the inflammation subsides, the effusion in the cavity gradually changes from purulent to serous.

Tubal obstruction

In most cases, patients with tubal obstruction have developed into chronic infection when they go to the hospital to confirm the examination, showing chronic interstitial salpingitis. At this time, the fallopian tube wall has been infiltrated by lymphocytes, and the epithelial cells of mucosa have become hypertrophy. After a long time, the tissue will fibrosis, and the fallopian tube will thicken or curl up. All these will eventually lead to infertility.

Salpingitis

Severe oviduct inflammation can cause complete obstruction of fallopian tube. Although some inflammation does not cause blockage of fallopian tube lumen, the intima is destroyed by inflammation, which affects the ciliary movement of intimal cells, and the oviduct wall is stiff due to scar formation, which affects the peristalsis of fallopian tube. Thereby affecting the encounter and transportation of sperm and eggs, resulting in infertility. Salpingitis can also be secondary to inflammation of organs or tissues around fallopian tubes, especially inflammatory adhesion around fallopian tube umbrella or ovary, so that fallopian tube umbrella can't inhale discharged egg cells into egg tube and meet sperm, such as suppurative appendicitis and tuberculous peritonitis.

Patients with adnexitis, suppurative appendicitis, tuberculous peritonitis, tuberculosis, endometriosis, patients with incomplete abortion, fever, abdominal pain and puerperal infection after induced abortion, patients with sexually transmitted diseases such as gonorrhea and patients with fallopian tube malformation may all lead to abnormal fallopian tube function and tubal infertility.

Adhesion of fallopian tube

Adhesion of women's fallopian tubes will lead to tubal nowhere. If the fallopian tubes are completely adhered, there will be no chance of natural conception, and abdominal discomfort may occur in acute stage. In recent years, due to the increasing number of uterine infections, sexually transmitted diseases, endometriosis and other diseases, All kinds of inflammation cause local tissue hyperplasia of fallopian tube and then adhesion. Once fallopian tube obstruction occurs, even if the egg has been fertilized, it cannot enter the uterus and become pregnant. If it stays in the fallopian tube for development, it may become a dangerous ectopic pregnancy.

Salpingitis

Acute salpingitis lesions are mainly endometrial inflammation, and if they come from acute pelvic inflammatory disease, the lesions are extensive. Fallopian tubes and other tissues are congested and exudated, and purulent exudates in the cavity flow into the pelvic cavity, causing pelvic peritonitis, and pelvic abscess is formed in severe cases; Inflammation spreads to ovaries, forming tubal ovarian inflammation or abscess; If tubal fimbria adhesion atresia can form tubal pyorrhea, it is more common in acute attack of chronic inflammation. Pathogenic microorganisms can often be found in exudates, pus and mucosal surfaces of acute inflammation. Acute inflammation is not treated in time, or the treatment is not complete, it can be turned into chronic salpingitis; Acute attack of chronic tubal inflammation is characterized by acute inflammation. The oviduct is red and swollen with naked eyes, and the pelvic organs are also inflammatory changes such as congestion, edema and exudation. Pus may flow out when pressing the oviduct, and pelvic abscess changes such as oviduct and ovary may be seen.
